Honestly... nothing. Now that you've bought it, it doesn't really do much good to ask what you should look for, does it? I mean, really... people should ask these questions prior to purchasing something, don't you think?

As far as safety goes, cylinder lock up is probably the best thing you've already checked, but take a peek down the barrel (unloaded of course) and check for any bulges or signs of a stuck round or squib load.

Wasn't insulting you. Please try to remember that you're not the only one reading stuff on this site. So, by my saying that people should ask first before buying, I was answering your question by point out looking at the barrel AND trying to help other people out by trying to get them to ask questions first.

I even commended you for checking the cylinder lock up. The only other thing that I'd worry too much about, I pointed out as being the barrel.

I'm not entirely sure where you thought I was busting your balls. I could care less about post count.

Cylinder gap can also present problems, but none that will totally fubar the pistol unless it's just huge. It can be fixed by a competent gunsmith if it's too large. Not knowing your experience level with revolvers, make sure to keep your digits away from the cylinder gap so you don't lose them. (No, I'm not calling into question your knowledge, I just don't know how much you may know)

ahh sheet...

I'm going to edit my post to hide my over reaction...but now see that my faux pas will live on in the quote...sheesh...i can't even foul up correctly today...

But above all else, thanks for your responses - i'm not an amateur, but I'm no pistolsmith either and I was genuinely interested in hearing what else I could or should check before I burned some gunpowder in this thing.

I suggest you take it to an expert gunsmith, and let him do all the looking and measuring and such. Money well spent for piece of mind, especially if he finds a potential problem. I have bought my share of used handguns and have always had them checked by an expert (which I most definitely am not). Being a Smith and not real old you should be fine, but better safe than...you know!
Good luck,
